Question:
A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency.
Solution:
Time period = t/Number of oscillations in time t = 4/40 = 0.1 s
Frequency = 1/Time period = 1/0.1 = 10 Hz
Time period = t/Number of oscillations in time t = 4/40 = 0.1 s
Frequency = 1/Time period = 1/0.1 = 10 Hz
